Threats to Garen with this build

Easy , very easy .. garen has been made to ravage akali everywhere if she uses her circle to go invisible use your E to harras her

2

Teemo

play safe , if he tries to blind you - use "w" and after 6 if you get near him with your Q he's dead

2

Pantheon

with him you must know when to engage and when not to , after thornmail you can go fight him and also make sure you hit him with a basic so his passive won't stop your Q and when he uses his E you must just use shield and spin for win in him

2

Gangplank

build armor and you win it easy

2

Nasus

Fun as hell when he aproches a near death minion to farm his q just hit hi with your q and he will be easy prey

2

Renekton

after he uses slice'n dice once you use q ,e,w and ulti

2

Jax

Farm and wait at least till lvl 3 to have one point in your skills , then w,e,q and you win the trades

2

Lee Sin

Silence then BOOOM!!

3

Fiora

just wait till she uses her riposte , after lvl 6 charge in her like a madman ... and don't forget thornmail

3

Zed

play safe , do not engage till you know you can kill him . When he uses his shadow to get near you use Q and keep your W for his ulti .

3

Jayce

play safe and build armor , after 6 he it's easy win

Wukong

Mordekaiser

Max your q and destroy his armor with your e while using shield for less dmg :D

4

Dr. Mundo

get ignite and dodge his cleaves , after lvl 6 he will regret that he stacked hp :D

7

Gnar

Gnar is really strong and at the moment bugged so it will be hard vs him if he gets mega gnar you have more chances to kill him + your ulti is perfect for mega gnar

8

Darius

he is very hard ... if you'r not used to play garen i advice you to not even think fighting him .. but if you have bad luck and find yourself on top with him ask for ganks and wait until you get ulti .
Never engage low hp unless you are sure you can win

9

Volibear

dunno why but he is really hard to fight in lane and it's annowing to have him on top . The one who gets farmed first wins .

Introduction

You must know this : Garen is op . Most of the players don't know this but if you master garen you don't have counter . YOu can do tower dives only with a giants belt on you and your W . Most people don't play garen becouse he is cheap and they don't even know his skills , use the element of surprize . And don't go full ad ... it's not a wise choice , garen does great dmg with only sunfire , thornmail and warmong (vs ap you get maw and then warmong and you will be good enough) .

Summary

I started playing Garen after i saw that he counters many champions , after the first games with him i said that i will never play him again but then i became bored of my other champions and after i mastered mundo i wanted to master another champ so i picked garen . After seeing how easy he can do anything i started to like this champ . I recommend every player to try and understand that even the cheapest champions in lol can be strong and i mean very strong ....

Pros and Cons

Pros
You have high sustain
High regen from passive and potion even at low levels
Good dmg
Great farming with E
If you lose early game you can come back mid or late
You can tower dive whenever you want
Your ulti is insane and has nice animation :-D

Cons
If you are not used to garen don't play agressive becouse you will get owned
Until you get 6 you can't easy kill any1

Farming

Farming is the most important thing if you want to win with garen . If you can't farm being agressive then stay under turret and farm . Remember you are not adc , mage or ad champ you are an stong tank that can get lots of kills but that is mid-late game , early game just Farm .

Team Work

If you owned you lane you can go help mid after you destroyed the first turret , your teleport will help you get back top if needed . Garen is very good at ganking and killing mid laners becouse most of them do not have too much hp or armor but be careful not to be killed .
Usually in team fights you will charge first , but try to take them from behind becouse your burst can kill theyr adc so your team has an advantage.
